HORTICULTURAL IMPLEMENT.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed December 81, 1906. Serial No. 350,218.

I To all whom it may concern:

' a valve 5.

Be it known that 1, DAVID CRAIG, a citizen of the United States, and aresident of Melrose, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements inHorticultural Implements, of which the following is a specification.

My invention relates to a horticultural implement designed to apply aninsecticide, such as creosote, in liquid form or in solution, to trees,shrubs and vines.

In the accompanying drawings which illustrate an embodiment of myinvention,-Figure 1 is an elevation of the implement; Fig. 2 is alongitudinal central section of the implement, enlarged; Fig. 3 is across section on line 33 of Fig. 2; and Fig. 4 is an elevation of thetop head presently to be described.

Referring to the drawings, 1 represents a pole. At the bottom of thepole is a reservoir 2 to contain an insecticide in liquid form. Thisreservoir is preferably cylindrical as shown, and has at its top thesleeve 3 into which the lower end of pole 1 fits and by which pole 1 issupported. Extending throughout the length of the pole is a duct 4 forconveying the liquid from the reservoir to the top of the pole. Thisduct is controlled by The duct 4 is preferably made of metal piping, andfor convenience and economy of manufacture,- preferably lies along theoutside of the pole 1 as shown in a slot or groove 6 provided therefor,excepting at its two extremities, where the pole is cut away so that thetwo ends of the duct may by being turned inwardly be located centrallyof the pole as shown. An extension 7 of the duct 4 is provided leadingdown into the lower part of the reservoir 2.

Secured within the upper wall of the reservoir at the side not occupiedby the sleeve 3 is an air pump comprising the cylinder 8, piston 9 andcheck valve 10, all being contained within the reservoir. The piston 9is preferably made of leather and is held between the metal cup 11 andwasher 12 by means of the nut 13. The pump is operated by the pump lever14 which is forked as shown at 15, 15, and provided at its outer endwith the handle 16. The forked ends of the lever are pivotally connectedwith the sleeve 3 supporting the pole as shown at 17, 17 The piston rod18 is pivotally connected at its lower end with the piston and at itsupper end is provided with the cross bar 19, which is journaled ateither end in the forks 15, 15 of the lever 14. An inlet port 20 isprovided in the reservoir through which the reservoir may be filled. Theport 20 is securely closed by a screw cap 21.

At the upper end of the pole, a top piece 22 is secured in any suitableway, as by screws, and has the projection 23 provided with a screwthread. A smaller the projection 24.. The nozzle 25 is flattened, asbest shown in Fig. 4, in order that it may be readily passed between thebristles of the brush presently to be described.

Screwed on to projection 23 is the top head 26 which consists of aferrule provided with the extended or flaring brush support 27 The brushsupport 27 is preferably curved upwardly at either side as shown in Fig.4, the curve being transverse to the lines in which the bristles of thebrush lie. It will be understood, however, that such curve is notessential. 28 represents a brush mounted upon said top head and brushsupport with the nozzle 25 extending into the midst of the bristles ofthe brush, the brush being removably secured in place by cords or likefastenings 29 which pass around the brush and through the eyelets 30provided for that purpose upon the bottom of the brush support 27.

The operation of the implement is as follows: The reservoir 2 is filledwith the solution to be used, through the port 20, up to a level whichmust be below the discharge orifice 31 of the pump. The screw cap 21 isthen tightly secured and the valve 5 closed. The air pump is thenoperated by means of the handle 16 until an air pressure is createdwithin the reservoir on top of the liquid sufficient to force the liquidupward through the duct 7 which extends nearly to the bottom of thereservoir and into the liquid, and through duct 4, and

into the brush. The brush can then be supplied with the desired amountof liquid by operating the valve 5 by means of the valve handle 32. Whenthe air pres sure within the reservoir falls to such a degree that itwill no longer force the liquid upward to the end of the duct, the airpressure may again be increased as above described by means of the pump.

The brush 28 is made removable in order that it may be interchanged withother brushes of other shapes or sizes, or in order that it may readilybe replaced when it becomes worn out.

I claim:

1. An implement of the character described, comprising a pole, areservoir at the bottom of the pole, a duct leading from the lower partof the reservoir to the top of the pole, means for compressing the airwithin the reservoir to force liquid contained within the reservoirupward through the duct, and a valve to control the duct.

2. An implement of the character described, comprising a pole, areservoir at the bottom of the pole, a brush removahly secured to thetop of the pole, a duct leading from the lower part of the reservoir tothe top of the pole and discharging into the midst of the bristles ofthe brush, means for compressing the air within the reservoir to forceliquid contained within the reservoir upward through the duct, and avalve to control the duct.

3. An implement of the character described, comprising a pole, areservoir at the bottom of the pole, a duct leading from the lower partof the reservoir to the top of the pole, a valve to control said duct,and means to compress the air within said reservoir, consisting of apump having a cylinder, piston and check valve, all contained within thereservoir. i i

4. An implement of the character described, comprising a pole, areservoir at the bottom of the pole, a duct leading from the lower partof the reservoir to the top of the pole, a valve to control said duct, apump communicating with the upper part of the reservoir to compress theair within said reservoir, and a pump lever having a forked endembracing and being pivotally attached to the pole.

An implement of the character described, comprising a pole, a reservoirat the bottom of the pole, a duct leading from the lower part of thereservoir to the top of the pole, a valve to control said duct, an airpump secured within the top wall of the reservoir and having itscylinder, piston and check valve all contained within the reservoir, thepump lever having a forked end embracing the pole and pivotallyconnected therewith, and the piston rod having its outer end pivot-allyconnected with said pump lever.

(S. An implement of the character described, comprising a pole, areservoir at the bottom 01 the pole, a duct leading from the lower partof the reservoir to the top of the pole, means to force liquid from thereservoir upward through the duct, and a nozzle at the upper end of theduct projecting beyond the end of the pole, flattened, and insertedbetween the bristles of a brush.

7. An implement of the character described, comprising a pole. areservoir at the bottom of the pole, a duct leading from the lower partof the reservoir to the top of the pole, means to force liquid from thereservoir upward through the duct, a brush removably secured to theupper end of the pole transversely thereof, and a nozzle at the upperend of the duct projecting beyond the end of the pole and dischargingamong the bristles of the brush, said nozzle being flattened tofacilitate inserting it between the bristies.

8. An implement of the character described, comprising a pole, areservoir at the bottom of the pole, a duct leading from the reservoirto the top of the pole, means to force liquid from the reservoir upwardthrough the duct, a top head comprising a ferrule and a flaring orextended brush support, and fastenings adapted removabiy to secure abrush to said brush support.

9. An implement 0f the character described, comprising a pole, areservoir at the bottom of the pole, a duct leading from the reservoirto the top of the pole, means to force liquid from the reservoir upwardthrough the duct, a top head mounted at the top of the pole having aflaring or extended brush support, and a brush removably secured to thebrush support by cords passing underneath the brush support and over thebrush,
